Is there anyway to force window decoration to be applied for all applications

[Neko-Box-Coder]

Hi,

Is there anyway to force window decoration to be applied for all applications, even when it has client side decoration.

I use the shade feature heavily, and it is impossible to do so with some applications since they use CSD. Some can be configured, some can't.
It would be great if openbox can be configured to "force" its own window decoration on them.

I tried with

<applications>
        <application class="*">
            <decor>yes</decor>
        </application>
</applications>

but didn't work for those applications.

Thanks.
